Ultra fine filters
AL/ST 150
The micfil AL/ST 150 0.5 µm is the ideal filter for all types of trucks, buses, construction machinery, generators, and boats.

Ultra fine filter, ideal for all types of trucks, construction machinery, generators, and boats.
The micfil AL/ST 150 0.5 µm is the ideal filter for all types of trucks, buses, construction machinery, generators, and boats.
With a diesel/petrol flow rate of up to 300l/h and an engine oil volume of max. 50l in bypass installations, it is also suitable for use under extreme conditions.
The micfil Al(Aluminium)/ST(Stainless Steel) 150 oil and fuel filter prevents abrasion in the machine for bearings, sleeves, and all moving oil-lubricated parts in the engine as well as in the diesel area for injection pumps and injectors. The use of our micfil ultra-fine filter prevents deposits in the combustion chamber, stops abrasion (in piston rings, injectors), and thus achieves a much improved and cleaner combustion.
The special features of the filter include a low price and easy maintenance. The installation leads to a much longer life expectancy of your engines and machines.
The filter can be used as a bypass filter for engine oil, in hydraulic, turbine, gear oil as well as for biofuels and bio-oil (see datasheet).
The micfil AL/ST 150 is suitable for both commercial and private use.
